Description

Technical Field

[0001] This utility model relates to an injection mold, and more particularly to a guide device for an injection mold and an injection mold. Background Technology

[0002] Injection molds are specialized tools used in plastic injection molding processes. They are used to inject heated and molten plastic into a mold cavity, and after cooling and solidification, a finished product is obtained. They are widely used to produce various plastic parts and products with complex shapes and precise dimensions, and are especially suitable for mass production, such as automotive parts, electronic housings, home appliances, toys, daily necessities, and electrical appliance housings.

[0003] Existing injection mold guiding devices are generally composed of guide pillars of the upper mold and guide cylinders of the lower mold. When the lower mold moves downward, the guide pillars extend into the guide cylinders for guiding and limiting. However, this guiding method is separate from the mold closing method, resulting in poor overall integrity during use. Furthermore, the mold is pushed by a single pushing component. After prolonged use, the connection between the mold and the pushing component may loosen, even causing the upper mold to shift and fail to align with the lower mold, thus affecting the mold closing effect. Summary of the Invention

[0004] The purpose of this utility model is to provide a guiding device and an injection mold for injection molds, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a guiding device for injection molds and an injection mold, comprising a mounting frame, a lower mold and an upper mold, wherein the lower mold is disposed inside the mounting frame, the upper mold is disposed on the upper side of the lower mold, and an upper mold base is connected to the upper side of the upper mold;

[0006] The upper mold base has symmetrically arranged insertion slots inside, and internally threaded guide pins are inserted into the insertion slots. The internally threaded guide pins are threadedly connected to the guide screw. An insertion block is connected to the upper side of the guide screw. The insertion block is connected to the rotating seat through a positioning bolt. The upper side of the rotating seat is rotatably connected to the mounting frame through a bearing seat. A guide cylinder is connected to the upper side of the mounting frame. The insertion dimensions inside the guide cylinder match the insertion dimensions outside the internally threaded guide pin. A drive motor is provided on the upper side of the internally threaded guide pin.

[0007] Preferably, a transmission gear is connected to the outer side of the rotating seat, and the outer side of the transmission gear meshes with the drive gear.

[0008] Preferably, the middle part of the drive gear is connected to the output end of the drive motor via a coupling, and the bottom of the drive motor is connected to the mounting frame.

[0009] Preferably, the internal threaded guide post has a positioning groove 1 and a positioning groove 2 inside, a positioning block 1 is inserted into the positioning groove 1, and one side of the positioning block 1 is connected to the upper mold base.

[0010] Preferably, a positioning block two is inserted into the interior of the positioning groove two, and an installation groove is provided inside the upper mold base. The interior of the installation groove is elastically connected to the positioning block two through a reset spring. An abutment block is connected to the outer side of the internal threaded guide post, and the abutment blocks are symmetrically arranged on both sides of the upper mold base.

[0011] An injection mold, wherein the upper side of the mounting frame is connected to a lower mold via a lower mold base, and the insertion dimensions inside the lower mold match the lower dimensions of the upper mold.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. To enable rapid guiding and docking of the lower and upper molds during use, the drive motor is activated during mold closing. The output of the drive motor, via a coupling, drives the drive gear to rotate and mesh with the transmission gear. The transmission gear drives the rotating seat, the insertion block, and the guide screw to rotate. Furthermore, under the threaded action of the guide screw and the internal threaded guide post, the internal threaded guide post moves downwards to engage with the guide cylinder. This injection mold guides the mold's movement through the internal threaded guide post, guide cylinder, and guide screw. The combination of the mold closing and guiding processes during use improves overall integrity, and the connection between the upper mold and the internal threaded guide post is less prone to shifting over long-term use.

[0014] 2. When disassembling and repairing the internal threaded guide post and guide screw, rotate the positioning bolt to remove it, then push the positioning block two until it disengages from the positioning groove two. At this point, the internal threaded guide post can be removed horizontally along the insertion groove. When installing the internal threaded guide post, push the positioning block two again and insert the positioning groove one into the positioning block one. Release the positioning block two, and the return spring will push the positioning block two outwards to insert it into the positioning groove two, allowing the internal threaded guide post to be installed. This utility model allows for quick disassembly and repair of the internal threaded guide post and guide screw. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 This utility model provides a technical solution: a guiding device for injection molds, including a mounting frame 1, a lower mold 2 and an upper mold 202. The lower mold 2 is arranged inside the mounting frame 1, the upper mold 202 is arranged on the upper side of the lower mold 2, and the upper mold base 203 is connected to the upper side of the upper mold 202.

[0022] The upper mold base 203 has symmetrically arranged insertion slots 3 inside, and an internal threaded guide post 301 is inserted into the insertion slot 3. The internal threaded guide post 301 is threadedly connected to the guide screw 303. An insertion block 304 is connected to the upper side of the guide screw 303. The insertion block 304 is connected to the rotating seat 305 through a positioning bolt 306. The upper side of the rotating seat 305 is rotatably connected to the mounting frame 1 through a bearing seat. A guide cylinder 302 is connected to the upper side of the mounting frame 1. The insertion dimensions inside the guide cylinder 302 match the insertion dimensions outside the internal threaded guide post 301. A drive motor 402 is arranged on the upper side of the internal threaded guide post 301. A transmission gear 4 is connected to the outer side of the rotating seat 305. The outer side of the transmission gear 4 meshes with the drive gear 401. The middle part of the drive gear 401 is connected to the output end of the drive motor 402 through a coupling. The bottom of the drive motor 402 is connected to the mounting frame 1.

[0023] In specific implementation, to enable the lower mold 2 and the upper mold 202 to achieve rapid guiding and docking during use, the drive motor 402 is started when the mold is closed. The output end of the drive motor 402 drives the drive gear 401 to rotate through the coupling. When the drive gear 401 rotates, its outer side meshes with the transmission gear 4, driving the rotating seat 305 connected to the transmission gear 4 to rotate. This, in turn, drives the insertion block 304 connected to the rotating seat 305 through the positioning bolt 306 and the guide screw 303 at the bottom of the insertion block 304 to rotate. When the guide screw 303 rotates, under the action of the thread on its outer side and the internal thread guide post 301, it drives the internal thread guide post 301 to move downward. At this time, the guide screw 303 and the internal thread guide post 301 can guide the movement of the upper mold 202. Furthermore, as the internal thread guide post 301 continues to move downward, the lower side of the internal thread guide post 301 will insert into the guide cylinder 302, again guiding the mold closing of the lower mold 2 and the upper mold 202. The injection mold guides the movement of the mold through the internal threaded guide post 301, guide cylinder 302 and guide screw 303. When in use, the mold closing process and the guiding process of the injection mold are combined to make the overall integrity better, and the connection between the mold 202 and the internal threaded guide post 301 is not easy to shift after long-term use.

[0024] See Figures 2-4 It can be seen that the internal thread guide post 301 has a positioning groove 1 5 and a positioning groove 2 502 inside. The positioning groove 1 5 has a positioning block 1 501 inserted inside, and one side of the positioning block 1 501 is connected to the upper mold base 203. The positioning groove 2 502 has a positioning block 2 503 inserted inside. The upper mold base 203 has an installation groove 504 inside. The installation groove 504 is elastically connected to the positioning block 2 503 through a return spring 505. The external side of the internal thread guide post 301 is connected to an abutment block 506, and the abutment blocks 506 are symmetrically arranged on both sides of the upper mold base 203.

[0025] In practice, when it is necessary to disassemble and repair the internal thread guide post 301 and the guide screw 303, after rotating and removing the positioning bolts 306 at the insertion block 304 and the rotating seat 305, push the positioning block 2 503 elastically connected in the mounting groove 504 of the upper mold base 203 until the outer side of the positioning block 2 503 disengages from the positioning groove 2 502 inside the internal thread guide post 301. At this time, the internal thread guide post 301 can be removed horizontally along the insertion groove 3. When installing the internal thread guide post 301, push the positioning block 2 503 again and remove the internal thread guide post 301. Positioning groove 5 on one side is inserted into positioning block 501. Positioning block 503 is released, and the return spring 505 pushes positioning block 503 outwards, allowing it to engage with positioning groove 502 inside the internal threaded guide post 301. This allows the internal threaded guide post 301 to be installed. Furthermore, the outer side of the internal threaded guide post 301 is provided with abutment blocks 506 that abut against both sides of the upper mold base 203. These abutment blocks, along with positioning groove 5, positioning block 501, positioning groove 502, and positioning block 503, ensure more stable operation of the internal threaded guide post 301. This invention allows for quick disassembly and maintenance of the internal threaded guide post 301 and guide screw 303 used for guiding and driving.

[0026] The upper side of the mounting frame 1 is connected to the lower mold 2 via the lower mold base 201, and the insertion dimensions inside the lower mold 2 match the lower dimensions of the upper mold 202.

[0027] In summary, when using this injection mold, the drive motor 402 is started. The output end of the drive motor 402 drives the drive gear 401 to rotate through the coupling. It meshes with the transmission gear 4, causing the rotating seat 305, the insertion block 304, and the guide screw 303 to rotate. Under the action of the thread with the internal thread guide post 301, the internal thread guide post 301 moves downward and inserts into the guide cylinder 302 connected to the upper side of the mounting frame 1 until the upper mold 202 connected to the bottom of the upper mold base 203 is fully connected to the lower mold 2 connected to the upper side of the mounting frame 1 through the lower mold base 201. The contents not described in detail in this description are existing technologies known to those skilled in the art.
